Real Interns, Real Results at Blockspoon — A One-Month Record | Digital Badges
Three Blockspoon interns — a growth marketer and two Android developers — completed meaningful real-world projects in a single month and shared blockchain-issued digital badges as proof on LinkedIn.
Today we want to share a slightly special story. Growth marketer Jina, Android developer Taeyoung Kim, and Minjun Kim. It was the day these three super-interns wrapped up their one-month journey and headed out.
“Are they really interns?” — all three delivered results that pulled this question out of us. Jina handled everything from content marketing management to product and marketing data analysis, proposing new strategies. Taeyoung and Minjun completed the Kolleges Android app development and submitted it to the Play Store for review.

We had our final lunch together and chatted about everything we’d been too busy to talk about. We’re putting the last questions on the blog to preserve them.
Q. Was your time interning at Blockspoon helpful?
I got to do real data analysis in a working context and worked with BigQuery, which I hadn’t really used before. I grew a lot in both proficiency and insight, and most importantly I feel proud that I contributed positively to Kolleges’s growth.
The Android developer duo also showed great teamwork.
Working with Minjun on app development meant we could complete it in a short amount of time. The fast feedback from the other developers and designers made the work really fun.
I was very satisfied. The scope of the work was exactly right for the timeframe, and it was a hugely beneficial experience for my developer career. The frontend and backend developers handled requests fast, so the work was satisfying.

Q. Would you recommend the one-month internship program operated by Team Sparta to your friends and acquaintances?
If you have ambition for your own job role, you can take away a lot.
It really depends on the company. A friend of mine went to another company as an intern and just sat around for a month doing nothing. It was easy, but they got nothing out of it.
I also think company choice is critical. We had an already-commercialized web service, which made it easy to build the app — but a friend of mine had to build an app within a month from a state with no source code, and they’re pulling all-nighters every day.

Q. How was your experience receiving a digital internship certificate and sharing it on LinkedIn?
They say proof matters in today’s job market, right? It was novel and great to be able to prove my experience with an NFT digital badge. After sharing it on LinkedIn, a lot of people in my network paid attention.
At first I wasn’t sure what a digital badge was, but knowing it’s issued on the blockchain made it feel even more special. It feels like one more unique experience added to my portfolio.
When I shared the certificate with friends and colleagues, other developers asked a lot about the one-month internship program. There seem to be many people who want short, intensive practical experience like I had.

It was a short month, but all three of them seem to have walked away with real-world experience, growth, and enjoyment. We’re looking forward to seeing them grow even more from here. 😊
